Wheel-build advantages that matter on the trail

1. 60T ENVE Innerdrive ratchet - Delivers quick engagement for responsive pedal pickup when accelerating out of corners, clearing tech, or ratcheting through punches
2. MicroSpline freehub compatibility - The correct interface for modern MicroSpline cassettes, supporting current MTB drivetrain setups without adapters
3. Boost rear hub platform - Built for Boost-spaced frames and wheel builds, supporting the stiffness and tire/frame clearance targets of today’s trail and enduro bikes
4. 7075-T6 aluminum hub shell - High-strength material choice for a stiff, durable foundation that holds up under hard riding and high spoke tension
5. Fully serviceable design - Replacement parts availability supports real-world longevity, making periodic bearing and drive maintenance straightforward over the life of the hub
6. Optional ratchet rings (sold separately) - Allows future tuning of engagement feel and service strategy without replacing the complete hub

Available in multiple anodized color options to match custom mountain bike builds.
